SKELETON LID.

Specification of Letters Patent.

Patented Dec. 5, 19 16.

Application filed October 15, 1915. Serial No.55,924:.

To all whom it may concern Be it known that 1, CHARLES G. MANZ, a

citizen of the United States, residing at' New Kensington, in the countyof West moreland and State of Pennsylvania, have invented certain newand useful Improvements in Skeleton Lids, of which the following is aspecification.

This invention relates to skeleton lids designed for use in connectionwith the burners of gas or oil burning stoves and may be more properlytermed an economy lid, as it is designed to confine the flame as well asthe fumes in such manner that they will be concentrated upon the utensilor other receptacle which the lid supports.

The main object of my invention resides in a construction of collarmember attachably mounted in connection with the lid proper anddepending in such manner as to encircle the gas burner.

In this connection, it is also an object of my invention to so constructthe lid that a plurality of sets of flanges are provided, in connectionwith any of which the depending collar may be used to increase ordecrease its diameter, as may be desired. 7

A further object of my invention resides in so constructing the lid thatadjustments are provided whereby this lid may be adapted to varioussizes of stove hole openings,

it being desirable to provide these adjustments in order to preventforth of the skeleton lid.

The preferred embodiment of my invention is shown in the accompanyingsheet of drawings, in which similar characters of reference designatecorresponding parts, and in which:

Figure 1 is a partial plan view ofmy imshiftingback and 'proved type oflid, Fig. 2 is a side elevation of the structure shown in Fig. 1 with aportion of the collar broken away, and, Fig. 3 is a bottom view of thestructure shown in Fig. 2.

In these several "iews, the lid itself is formed of a general framework,this general framework comprising a circular frame piece 1 and aplurality of radially inwardly extending fingers 2, which latter may beconnected with each other for purposes of stability as is shown at 3.These fingers all extend inwardly a distance to leave an open space suchas shown at 4 adjacent their eX- treme inner ends. The underside of thegeneral framework is also provided with a plurality of dependingsegmental flanges arranged in sets, the flanges designated 5 beingdisposed at a point nearer the center of the lid as a whole than thosedesignated 6. cooperatively mounted V in connection with these flangesis a depending collar 7, which collar is preferably of ribbon natureformed to assume the shape ofa circle as is shown in the drawings, theoverlapping ends of this ribbon being shown at 8. This collar comprisesan outside metal base member 9 whose upper and lower edges are turnedover as is shown at 10 to securely clamp layers of as bestos 11 or othersimilar material between them. This collar i's'securely held in positionwith either set of flanges by means of the wires shown at 12, thesewires being of suflicient stiflness, so that when their ends areturned'over as is shown at 13, a secure grip will be had.

The circular member 1 is formed with a series of radially arrangedslots, such as are shown at 14, the opposing walls of these slots beingserrated after the manner shown at 15. In order that the lid itself maybe adapted to various sizes of stove openings, I have made theseserrations of a size to receive the shanks'of bolts shown at 16 andbecause of their size it is impossible for them to slide back and forthwithin the slots ex- .cept after having completely withdrawn them. Inorder to prevent their dropping out of position, nuts 17 are threaded ontheir lower ends and moved into clamping engagement as is shown. Thesenuts then serve as the centering means to hold the lid as a wholecentered within the stove openings.

From the above description, it will be apparent that the collar member 7may be adjusted to assume various diameters since this collar member maybe bent to cooperate with either the inside or outside depending facesof either of the flanges 5 and 6, whereupon four different sizes will beattained. Also, this collar depending and encircling the gas burner willconfine all of the fumes and flames to concentrate them on the undersurface of any receptacle placed on top of the lid. Finally, by'means ofthe adjustment created'by the bolts 16, the lid may be adapted tovarious sizes of stove openings and in this manner the lid itself heldproperly centered both with respect to the gas burner and with respectto the stove opening.

An inspection of Figs. 1 and 2 will show that the radially arrangedfingers 2 are extended to a point slightly. above the upper generalribbed framework, and adjustable. means carried by said framework to fitit to the desired stove opening.

'eral" ribbed framework, a collar from the underside of said frameworkdeface of the circular frame piece 1, this arrangement being resorted toin order to permit the escape of the products of com- ,bustion and alsoto permit the flames to extend out through these openings should theyburn with sufficient intensity. YVhat I claim, is: j lylna skeleton lidfor gas burners, a

2.111 a skeleton lid for gas burners, a general'ribb'ed framework, saidframework being provided with a plurality of radially arranged slotswhose radial walls are serrated, and a bolt and nut in each of saidslots, said bolts fitting said serrations and forming the means foradjusting the lid to make it fit the desired stove opening.

3. In a skeleton lid for gas burners,a genepending flanges dependingfrom the underside of said framework, an attachable expansible dependingcollar designed to enclrcle the gas "burner and be attached to assumevarious sizesby means of said flanges, and means for attaching saidcollar to any of said flanges.

.5. In a skeleton lid for gas burners, a

general ribbed framework, a plurality of flanges depending from theunderside of said framework, an attachable expansible depending collardesigned to encircle the gas burner and be attached to assume varioussizes by means of said flanges, means for attaching said collar to anyof said flangessaid framework being provided with a series of radiallyarranged slots, and a bolt and nut in each of said slots adjustable toassume any desired position to fit the lid to the desired stove opening.

6. In a skeleton lid for gas burners, a general ribbed framework, aplurality of flanges depending from the underside of the framework atdifferent distances from its center, a ribbon designed to be bent to circular shape to cooperate with any of said flanges, and means for holdingsaid bent ribbon in connection with the flanges with which itcooperates.
